AASHTO M 335-19 PDF Download

The AASHTO M 335-19 standard is a comprehensive specification for steel-reinforced polyethylene (PE) ribbed pipe. It outlines the requirements and testing methods for this type of pipe, as well as couplings and fittings, for use in surface and subsurface drainage applications. The standard covers nominal sizes ranging from 300 to 1500 mm (12 to 60 inches).

Some of the key aspects addressed in the standard include materials, workmanship, dimensions, pipe stiffness, impact resistance, tensile strength of seams, shape stability, joining systems, and marking requirements. The steel-reinforced PE ribbed pipe is specifically designed for drainage purposes, where the soil provides support to its flexible walls. Common applications include culverts and storm drains for collecting and conveying drainage water through open gravity flow.

It is important to note that when using PE pipe in exposed locations, such as those susceptible to ultraviolet radiation, appropriate measures should be taken to protect the exposed portions due to the combustibility of PE and the potential effects of prolonged exposure to ultraviolet radiation. While this specification focuses on the material requirements of the pipe, the AASHTO LRFD Bridge Design Specifications and AASHTO LRFD Bridge Construction Specifications provide guidance on the structural design and installation procedures for steel reinforced thermoplastic culverts.
